Seal Once 1 gal. S Once Nano Exterior Stain

Seal-once has been leading the innovation in the use of nanotechnology to create long-lasting, Eco-friendly wood sealers and tinted wood stains since 2005. Our New and Improved nano Penetrating Wood Sealer, deeply penetrates the surface of wood to protect and stabilize against water damage and decay. Unlike many top-coat sealers that trap moisture below the surface, nano creates a long-lasting, flexible, breathable barrier, that allows water vapor to escape and help prevent damage. nano is warranted to prevent water intrusion for up to 10 years on vertical and 6 years on horizontal surfaces. Seal-once Nano Waterproofing Wood Sealer and Stain is ideal for use on unfinished interior and exterior wood surfaces. The clear, non-film forming formula allows the wood to age naturally without decay, morphing to a rich silver-gray over time. It can also be used as a wood stain, when mixed with a full range of semi-transparent tints to enhance the appearance and provide additional UV protection from sun rays.
